The bearing base includes a first bearing part and a second bearing part located outside the first bearing part. The first bearing part is made of plastic. The second bearing part is made of metal, and a slot is provided in the bearing seat. The lens module also includes colloid, and the gel is located in the slot to connect the first bearing part and the The second carrying part.

An embodiment of the present invention also provides an electronic device including the lens module.

The bearing seat in the present invention includes a first bearing part and a second bearing part located outside the first bearing part. The second bearing part is the outer wall of the bearing seat. Since the second bearing The material of the carrier part is metal, which has high strength. Compared with the plastic carrier seat in the prior art, the present invention can reduce the thickness of the carrier seat, that is, reduce the size of the carrier seat in the length and width directions, thereby The size of the lens module is reduced to meet the requirement of miniaturization of the lens module. In addition, the present invention also provides the slot on the load-bearing seat, and fills the colloid in the slot to connect the first load-bearing part and the second load-bearing part, thereby improving the load-bearing capacity. The strength and stability of the base are thereby improved, thereby improving the strength and stability of the lens module.
